Specification of Letters Patent.

Patented Feb. 11,1913.

Application filed March 20, 1912. SerialNo. 685,135.

To all whom it may concern:

Be it known that I, JOHN H. STARR, a citizen of the United States, residing at Danbury, county of Fairfield, State of Connecticut, have invented an Improvement in Attachments for Producing a Positive Length of Nap, of which the following is a specification.

This invention has for its object to provide an attachment for clipping machines adapted for general use and especially adapted for machines for clipping velour hat bodies, so called, which will permit the bodies to be readily inserted and removed and will clip the nap to a positive and uniform length without regard to the thickness of the body and will prevent injury to the bodies should there be thickened portions or should a body become folded or wrinkled. With these and other objects in view, I have devised the novel nap regulating attachment which I will now describe, referring to the accompanying drawing forming a part of this specification and using reference characters to indicate the several parts:

Figure 1 is a vertical section of a clipping machine with my novel attachment in place thereon showing its construction and mode of operation; Fig. 2, a view looking in the direction of the arrow in Fig. 1; and Fig. 3 is a detail view on the line-3-3 in Fig. 1, looking in the direction of the arrows.

10 denotes the bed of a clipping machine, 11 a clipping cylinder, 12 a swinging frame in which the cylinder is journaled, 13 the bed knife which cooperates with the clipping cylinder and 14: a plate by which the bed knife is carried and which is adjustably secured to the swinging frame. The swinging frame is shown as pivoted on a standard 15 which extends upward from the bed and as provided with an arm 16 fro-m which a treadle rod 17 depends and a depending arm 18 to which a spring 19 is connected. The other end of the spring is attached to a fixed portion of the machine (not shown) and its action is to raise and retain the clipping mechanism out of operative position, said mechanism being placed in operative position as in Fig. 1 by a downward pull upon the treadle rod, the

treadle' not being shown as specifically it forms no portion of the present invention. Standard 15 is provided with a bracket 20 through which arm 18 passes, said bracket carrying a set screw 21 which serves as a stop to limit the movement of the clipping mechanism when drawn down by the treadle rod. The screw is locked in position after adjustment by a set nut 22.

23 denotes a table or shoe over which the hat bodies are fed in use. This shoe is carried by a standard 24 which extends upward from the bed.

The feeding mechanism is not shown as specifically it forms no portion of the present invention. The parts enumerated may all be of any ordinary or preferred configuration or design but may advantageously be constructed substantially as shown in the drawing.

My novel attachment comprises essentially a regulating plate 25 which in use lies substantially parallel with the bed knife and the shoe and cooperates with the bed knife and clipping cylinder in producing a nap corresponding in length with the thickness of the regulating plate. It will be noted that in the operative position, (see Fig. l), the regulating plate lies over the forward end of the shoe, is substantially parallel therewith and is so located that at the instant the nap is subjected to the action of the clipping mechanism the nap will stand upright against the operative face of the regulating plate, the clipped nap being then drawn under the regulating plate and between said plate and the shoe. In practice, regulating plates may be provided of varying thickness to provide for different lengths of nap that may be required. The regulating plate is shown as carried by a plate 26 which is adjustably secured to a bracket 27 cast integral with or rigidly secured to standard 24.

28 and 29 denote studs rigidly secured to and extending upward from the carryingv plate. Stud 29 is provided with a shoulder upon which the outer end of the regulating plate rests, the shoulder being in horizontal alinement with the shoe as clearly shownin Fig. 2. Both studs pass through the regulating plate freely and stud 28 carries a spring 30, the opposite ends of which bear respectively against the carrying plate and the under side of the regulating plate. The action of this spring is to normally hold the regulating plate raised above the shoe as in Fig. 2, so that a hat body may be readily passed over the shoe and under the regulating plate. Relatively weak springs 31 bear against the upper side of the regulating plate and against nuts 32 at the upper ends of the studs. These springs are strong enough to retain the regulating plate in place but are weaker than spring 30 so that the instant the clipping mechanism is raised the regulating plate will be lifted thereby out of engagement with the shoe. The carrying plate is adjustably secured to the bracket by means of studs 33 which are rigidly secured to the plate, pass through slots 34 in the bracket and are engaged by thumb screws 35 which bear against the under side of the bracket. Lateral adjustment of the regulating plate relatively to the shoe may be effected by loosening the thumb screws and moving the carrying plate in either direction transversely of the bracket as may be required.

The operation of my novel attachment will be readily understood from the description. It being understood that the swinging arm and the clipping mechanism normally lie in a raised position (not shown in the drawing) and that in the operative position the regulating plate is engaged by the bed knife and pressed downward into engagement with a hat body on the shoe (see Fig. 1), it follows that having placed a hat body in position on the shoe the operator is simply required to draw downward on the pedal rod, which swings frame 12 and the clipping mechanism into operative position, and, through the engagement of the under side of the bed knife with the upper side of the regulating plate, moves the latter also into operative position, that is intoclose engagement with the hat body onthe shoe. Feeding of the hat bodies may be performed in any ordinary or preferred manner and the clipping operation may be performed as usual except that the length of the nap will be positively regulated by the regulating plate. Should portions of a hat body be thicker than others or should the body become folded or wrinkled, the body will not be injured by the clipping mechanism as the regulating plate and with it the swinging arm and clipping mechanism, will be correspondingly raised, leaving all portions of the nap of a positive and uniform length.

Having thus described my invention, I claim:

1. An attachment of the character described comprising a regulating plate adaptengagement with the shoe.

2. An attachment for clipping machines which comprises a shoe, and a clipping cyl inder and bed knife carried by a swlnging arm, said attachment consisting of a regulating plate adapted to lie between the shoe and the bed knife, a standard therefor, a carrying plate adjustably secured to the standard and means for yieldingly connecting the regulating plate to the carrying plate and for normally raising the regulating plate out of engagement with the shoe.

3. In a machine of the character described, the combination with a clipping cylinder and a bed knife and a swinging arm by which they are carried, of a shoe, a standard therefor, a regulating plate adapted to be held in engagement with a hat body on the shoe by the bed knife, a bracket carried by the standard and a yielding connection between the bracket and the regulating plate whereby the latter is normally raised out of operative position.

4. In a machine of the character described, the combination with a clipping cylinder and a bed knife and a swinging arm by which they are carried, of ard therefor, a regulating plate adapted to be held in engagement with a hat body on the shoe by the bed knife, a bracket carried by the standard, a carrying plate adjustably secured to the bracket and yielding connections intermediate thecarrying plate and the regulating plate, whereby the latter is normally held out of operative position.
